If You Run Into Problems
One useful way to find the source of problems is to isolate your system to the smallest
size where the problem still occurs and then note all the symptoms. This serves to
eliminate areas not involved in the problem and make finding the problem easier.
Once you’ve noted problem symptoms, look through the following table and see if any
of the symptoms are listed. If so, check the items listed. If you later need to call for
customer service, let them know all of the things you’ve tried and when and how the
symptoms appeared.
